This method returns true if the capture window duration has not elapsed yet, false otherwise.
Time m_captureWindow
Capture window duration.
static TypeId GetTypeId(void)
Get the type ID.
A base class which provides memory management and object aggregation.

TypeId SetParent(TypeId tid)
Set the parent TypeId.
Definition: type-id.cc:922
Ptr< const AttributeAccessor > MakeTimeAccessor(T1 a1)
